Overview
Mirror Lake is one of the most popular hikes in Mount Hood National Forest, and it earns every bit of that reputation. The 3.2-mile round trip climbs 700 feet through Douglas fir and hemlock forest to a small alpine lake at 3,900 feet, where the south face of Mount Hood reflects perfectly in the water on calm mornings. It's the photo you've seen on a hundred Oregon postcards.
The trail works for hikers of all levels. Families with young kids regularly complete it (children as young as 5 can handle the grade with some patience), and experienced hikers can extend the trip with a scramble up Tom Dick and Harry Mountain for one of the best panoramic views on the south side of the mountain. Dogs are welcome on leash. For less crowded alternatives on the same mountain, Elk Meadows on the northeast side and Tamanawas Falls on Highway 35 both offer similar or better rewards without the Government Camp parking situation.
The downside is the crowds. Mirror Lake is the most heavily trafficked trail in the Government Camp area, and on summer weekends the parking situation alone can be enough to make you reconsider. But get there early, or visit on a weekday, and you'll understand why people keep coming back.
The Route
Trailhead to Mirror Lake (1.6 miles, 700 feet gain)
The trail starts from a pullout along US-26 near milepost 52, just west of Government Camp. There's no formal parking lot, just roadside spots on both sides of the highway. A crosswalk helps you get across safely, but be careful: US-26 traffic moves fast through here.
From the trailhead sign, the path enters the forest immediately and begins a steady, moderate climb. The grade is consistent but never steep, switchbacking up through a forest of Douglas fir, mountain hemlock, and Pacific silver fir. The trail surface is well-maintained with packed dirt, occasional roots, and a few rocky sections. In the first half mile, you'll cross a couple of small footbridges over Camp Creek.
At about 1 mile in, the trail levels off briefly before the final push to the lake. You'll hear it before you see it: the trees thin, the trail flattens, and Mirror Lake appears on your left. The first view of the lake with Mount Hood rising behind it is genuinely impressive, even if you've seen the photos.
At the Lake
Mirror Lake is a small, shallow alpine lake, roughly 300 yards long and 150 yards wide. A trail circles the lake (about 0.5 miles), and you can walk the full perimeter to find your preferred spot. The best reflection views are from the south shore, looking north toward the mountain.
The reflection shot depends on conditions. Early morning (before 10 AM) is best, when the air is still and the water is glassy. By midday, afternoon thermals create ripples that break up the mirror effect. Overcast days can actually produce more dramatic photos than bluebird days, since the flat light enhances the reflection.
The lake is shallow enough to warm up for swimming by late July. It's not warm, exactly (expect water temperatures in the low 60s), but on a hot August afternoon it feels good. The east shore has a gradual, sandy entry point that works well for wading and swimming.
Tom Dick and Harry Mountain Extension (3 miles additional, 1,300 feet gain)
If the lake feels too easy or too crowded, keep going. A trail continues south from Mirror Lake up to Tom Dick and Harry Mountain, a 5,066-foot ridgeline with three distinct summits (that's where the name comes from). The additional hike adds about 3 miles round trip and 1,300 feet of elevation gain, making the total outing roughly 6.2 miles with 2,000 feet of total gain.
The trail to the ridge climbs steeply through subalpine forest, breaking out above treeline for the final push to the summit. The reward is a 360-degree panorama: Mount Hood fills the northern horizon, Mount Jefferson is visible to the south, and on exceptionally clear days you can spot Mount Adams and Mount Rainier to the north in Washington.
The scramble to the easternmost summit involves some loose rock and scrambling. It's not technical, but it's not a trail either. Use good judgment and watch your footing.
What to Expect
Trail conditions: The trail is in good shape for most of the hiking season. Snow typically clears by mid-June, though patches can linger in shaded sections into early July. The trail can be muddy in early season and after rain. By August, it's usually dry and dusty.
Crowds: There's no sugarcoating it: Mirror Lake is busy. On a sunny Saturday in July or August, you will share the trail with dozens of other groups. The lake itself can feel like a park picnic area. If that bothers you, go on a Tuesday, or visit in late September when the crowds disappear and the vine maple turns red and gold.
Bugs: Mosquitoes can be fierce at the lake from late June through mid-July, especially near the marshy north end. Bring repellent or a head net during peak bug season.
Wildlife: Gray jays are ever-present and will help themselves to any unattended food. Chipmunks are abundant near the lake. Occasionally you'll spot a pika on the rocky slopes above the lake, particularly on the way up to Tom Dick and Harry.
Cell service: Spotty to nonexistent at the lake. You might get a bar or two of Verizon at the trailhead since it's close to the highway, but don't count on it.
Seasonal Notes
Summer (late June through September): Peak season. Trail is snow-free, lake is swimmable (barely), wildflowers bloom in the meadows around the lake in July. This is when you'll see the most people.
Fall (October): One of the best times to visit. The vine maple and huckleberry bushes around the lake turn brilliant shades of red and orange. Crowds drop sharply. Bring layers, as morning temperatures can dip into the 30s at this elevation.
Winter (November through May): The trail is buried under snow and becomes a popular snowshoe route. The lake freezes over. It's a completely different experience: peaceful, quiet, and beautiful in its own way. Be prepared for route-finding, as trail markers are hidden under snow. An avalanche risk exists on the slopes above the lake, so check the Northwest Avalanche Center forecast before heading up toward Tom Dick and Harry in winter.
Spring (May through early June): The trail is typically a mix of mud, snow, and running water. The lake is partially frozen. Unless you enjoy postholing and wet feet, wait until mid-June.
Tips
Arrive early or visit midweek. The parking area holds maybe 20 to 25 cars. On summer weekends it fills by 9 AM, sometimes earlier. Cars parked illegally get ticketed. Your best options are to arrive by 7:30 AM, go on a weekday, or visit after 4 PM for a sunset hike.
No Northwest Forest Pass required. Unlike most trailheads in the area, Mirror Lake does not currently require a parking pass. This is one reason it's so popular.
Bring water and snacks. There's no potable water at the lake. The lake water can be filtered in a pinch, but it's easier to carry what you need for a 2- to 3-hour outing.
Keep dogs on leash. Dogs are allowed but must be leashed. The lake area is heavily used, and off-leash dogs create problems with other hikers and wildlife. Pick up after your dog.
Don't feed the gray jays. They'll beg shamelessly, but feeding wildlife teaches them to associate humans with food. It's bad for them and leads to more aggressive behavior toward future hikers.
If you're going to Tom Dick and Harry, bring trekking poles. The descent from the ridge is steep and loose in places. Poles make a real difference on the way down.
Getting There
From Portland, take US-26 East toward Mount Hood. The trailhead is at milepost 52, about 2 miles west of Government Camp. Look for the "Mirror Lake" sign on the south side of the highway. The drive takes about 1 hour and 15 minutes from downtown Portland in normal traffic. Ramona Falls is about 20 minutes north of Government Camp on Lolo Pass Road, making a natural companion hike if you want a full day: Mirror Lake in the morning, Ramona Falls in the afternoon. For the full picture of Hood hiking options, see the Timberline Trail page for the big loop that connects all of Hood's ecosystems.
From Government Camp, it's a 2-minute drive west on US-26. You can also walk from Government Camp along the road, though the highway shoulder is narrow and not particularly pleasant.
The nearest services (gas, food, restrooms) are in Government Camp, which has a few restaurants, a general store, and public restrooms near the visitor center. If you need a bigger grocery run, Sandy (about 25 miles west on US-26) is the last town with a full supermarket.
